How can I make it so I can afford this?

I am currently 7 months pregnant. I hate my job that I am currently working at full time. I recently moved back in with my parents so that money isn't as much of an issue and they would like to help with the baby. We recently talked about just quitting my job and going back to school. The only thing is that I have bad credit so I'm not sure if I can even get a loan or anything. And how would I make my car payment and pay for babysitting? I live in upstate New York (Syracuse). Any ideas??? I'm desperate....By the way I'm 21.
